beginner's questions about compiling on mac and windows

[redemption man]

i have created a simple tictactoe game using xcode on the mac and copiled it, and it works fine.
but when i compile the same thing on windows using c++ studio express it compiles but doesnt work as it should. i am only a beginner so i have mostly used if statments to make it, if any one can help me out or point out where i am going wrong i would be very appreciative.
